TECHNICAL FIELD

The subject matter disclosed herein relates generally to dentalappliances, and more particularly, to a dental appliance for use withsensing devices including bacteria sensors and/or pH sensors for sensinga pH level of saliva contained within an oral cavity.

BACKGROUND OF THE INVENTION

Dental plaque is a biofilm that forms naturally on teeth betweenbrushing and dental visits. Dental plaque can be a precursor to moresevere oral health problems including: dental caries, tooth decay,gingivitis, and chronic periodontitis. The occurrence of dentalcavities, gingivitis, and dental calculus are some of the most commonsystemic diseases of the body. In addition, oral diseases have beenshown to be an indicator of additional heath problems such as high bloodpressure, hypertension, and some cancers. Consequently, dentalpractitioners are in need of an adequate means to monitor and controlthe development of these oral diseases.

The oral cavity of the human body naturally produces saliva tofacilitate the breakdown of food during mastication. The saliva producedin the oral cavity may experience significant changes in pH levels.Changes in the pH levels of saliva within the oral cavity maysignificantly affect overall oral heath including causing an increase intooth decay and the formation of dental cavities.

At least some known oral pH sensors require substantially large dentaldevices that must be secured within the patient's mouth causingsignificant discomfort and distress for the patients. As such, it isdesirable to provide a dental appliance that facilitates supportingsensing devices within the oral cavity and reducing the discomfortexperience by the patient, thereby improving the overall health of thepatient. The present invention is aimed at the problem identified above.
